Magma decompression rates during explosive eruptions of Kīlauea volcano, Hawaii, recorded by melt embayments
The decompression rate of magma as it ascends during volcanic eruptions is an important but poorly constrained parameter that controls many of the processes that influence eruptive behavior. In this study, we quantify decompression rates for basaltic magmas using volatile diffusion in olivine-hosted melt tubes (embayments) for three contrasting eruptions of Kīlauea volcano, Hawaii. Incomplete e...
متن کاملDeep magma transport at Kilauea volcano, Hawaii
The shallow part of Kilauea’s magma system is conceptually well-understood. Long-period and short-period (brittle-failure) earthquake swarms outline a near-vertical magma transport path beneath Kilauea’s summit to 20 km depth. A gravity high centered above the magma transport path demonstrates that Kilauea’s shallow magma system, established early in the volcano’s history, has remained fixed in...
متن کاملRadiographic visualization of magma dynamics in an erupting volcano
Radiographic imaging of magma dynamics in a volcanic conduit provides detailed information about ascent and descent of magma, the magma flow rate, the conduit diameter and inflation and deflation of magma due to volatile expansion and release. Here we report the first radiographic observation of the ascent and descent of magma along a conduit utilizing atmospheric (cosmic ray) muons (muography)...
متن کاملTiming magma ascent at Popocatepetl Volcano , Mexico , 2000 ^ 2001
Magnetic anomalies may be used to constrain magma ascent and are useful as precursors to eruptions especially when correlated with other geophysical and geochemical data. In this paper we present multiparameter data on the magnetics, dome morphology, geochemistry and seismicity associated with the December 2000^January 2001 eruptions, the largest of the recent eruptions at Popocatepetl Volcano....
متن کاملForecasting magma-chamber rupture at Santorini volcano, Greece
How much magma needs to be added to a shallow magma chamber to cause rupture, dyke injection, and a potential eruption? Models that yield reliable answers to this question are needed in order to facilitate eruption forecasting. Development of a long-lived shallow magma chamber requires periodic influx of magmas from a parental body at depth. This redistribution process does not necessarily caus...
